2014 Silverado 2500HD MPG
Upgrade our 2011 Armada to a 2014 Silverado 2500 HD with the 6.0L V-8. What can I expect for gas mileage when towing about 9,000 lbs.

Whatever you got with the Armada towing should be the same. I get 8-10mpg with my 6.0L/6-spd/3.73 depending on speed and wind. I have never seen a gas engine tow a high walled RV get 12mpg. Budget for 8mpg and be happy with 9-10. I budget for 8mpg and can get that at 65-70mph towing. I get 10mpg closer to 60mph.
